The Extra Pass is a new daily column that’s designed to give you a better look at a theme, team, player or scheme. We’ve looked at the Northwest Division and Pacific Division, so let’s finish up the Western Conference with the Southwest Division.

San Antonio Spurs: 33-11, 1st in Southwest Division, $988,000 short of tax

Nothing new here. You can most likely add Tiago Splitter to this list as well — replacing his size and production with someone on a better contract is close to impossible, and the Spurs have other assets to dangle if they want to make a big move.

It’s no secret that the Spurs have been shopping DeJuan Blair for quite some time. With his contract expiring at the end of this season, they’ll be looking to get something — anything — in return. If the Spurs want to a make a move that nets them actual talent right now, Stephen Jackson‘s $10 million dollar expiring deal could provide cap relief for a team looking to trade a player on a longer contract.

Apologies to Matt Bonner and Boris Diaw, but the Spurs could use some real size defensively. Ayon just feels like a Spurs player — he’s a great passer, an excellent cutter, and he understands spacing. He’s one of those guys we’ll really start to appreciate once he gets on a winning team.

Chances of a deal: Low

Blair would likely already be gone if he could be dealt for anything of value. As for the rest of the roster, San Antonio could be a sneaky player in free agency if Manu Ginobili comes back at a reasonable price this offseason. After making some shakeups last year, the Spurs seem likely to sit this deadline out and wait until the summer.

Memphis Grizzlies: 26-14, 2nd in Southwest Division, roughly $2 million under the tax

Off-Limits: No one

After gutting their bench by trading Marreese Speights, Wayne Ellington, Josh Selby and a future first round pick just to get under the tax, the Grizzlies will almost definitely roll with their core for now. That said, Memphis is on an unsustainable path, and eventually they’ll need to trade Rudy Gay (or someone else) to get under the tax going forward. If someone bowls them over with an offer for any player on the roster, they’ll still listen.

Most likely to be dealt: SF Rudy Gay, ($16 million/3 years)

The Grizzlies will almost definitely stay put and ride out the rest of the season, but it’s basically only a matter of time before Gay gets shipped out. Now that they’re under the tax, selling whatever’s left of their bench (Bayless, Arthur) wouldn’t make any sense.

Player to target: The best the D-League has to offer

The Grizzlies will likely rely on D-League call-ups and minimum free agents from here on out, based mostly on the fact that they can’t add substantial salary if they want to stay under the tax.

Chances of a deal: Very Low

Unless they shockingly move a big piece, they’ve accomplished their goal of getting under the tax.

***

Houston Rockets: 22-21, 3rd in the Southwest, $18 million short of tax

Harden is already a star, and Parsons is set to make less than a million dollars over the next three seasons. Rockets GM Daryl Morey recognizes the value of that, and although teams may come knocking, he’s a cheap, productive building block going forward.

Crazy as it sounds, Delfino has the fourth largest contract on the team at just $3 million a year, which means if Houston wants to do anything big, they’ll likely need his deal to match salaries. Delfino is shooting nearly 39 percent from behind the arc this season so the Rockets likely don’t wantto trade him, but their hand might be forced if they target a big piece.

Is it worth forfeiting assets to woo a player for a short rental before they hit free agency? Maybe, maybe not, but it’s something the Rockets have to be considering with their hole at power forward and their struggles all year long on the defensive end. Pairing Smith’s athleticism at the 4 with Houston’s fast pace style seems like a match made in heaven, but it all depends on what Atlanta’s asking price is. That said, Atlanta should want to rebuild, and Houston has an enticing package of young frontcourt talent to offer.

Chances of a deal: High

Houston has to address their 19th ranked defense if they want to be taken seriously as a contender, and although waiting out Josh Smith or Dwight Howard to hit free agency this offseason may be the correct big move, there should be a variety of little deals available for Houston given their cap space. Just look how that worked out for Cleveland.

Dallas Mavericks: 18-24, 4th in Southwest Division, $10 million short of tax

Mark Cuban has said he won’t trade Nowitzki, and Dirk has a full no trade clause anyway. O.J. Mayo represents great value on his $4 million dollar deal, but he may be the only real attractive bait for opposing teams.

The Mavericks and Rick Carlisle clearly aren’t big believers in Collison, as they regularly opt for Mike James down the stretch of games instead. Collison isn’t a starting point guard in the league, but he could serve as a capable backup somewhere.

The Kings may be having a blowout sale on their roster, and the Bank of Cuban just may want to purchase a few assets on the cheap. Add in that getting a great center is Cuban’s Moby Dick, and the Mavericks could make a very convincing offer for Cousins based around alleviation of long-term salaries. A Dirk-DeMarcus frontcourt pairing would truly be fascinating to watch.

Chances of a deal: Very High

The Mavericks want to get Dirk some help in his last few years, and being a known buyer when teams are in fear of the tax that’s looming should grease the wheels a little bit. It’s hard to imagine the Mavs not making a move at the deadline.

***

New Orleans Hornets: 14-27, Last in Southwest Division, $6 million short of the tax

Davis is a given, but it’s probably safe to pencil in Ryan Anderson and Jason Smith for now as well. Eric Gordon is likely available, but if he can stay healthy and if the Hornets keep rolling, he’ll be much harder to have conversations about.

The Hornets oddly declined to pick up the option on Al-Farouq Aminu for next season, making him a free agent after this year. If a team were interested in taking a flier on the 22-year-old forward, it probably wouldn’t take much to pry him free. Although Aminu’s offensive game is still raw, he’s a terror in transition. The slow, grind-it-out pace of head coach Monty Williams doesn’t do him any favors. It would be fun to see a young, fast team like Charlotte take a chance on Aminu’s defensive potential.

How about an Aminu for Morrow swap? Aminu gets to go back home to Georgia where he’ll help fill Atlanta’s void at the 3. Anthony Morrow goes to New Orleans for a shot at more playing time (if he can’t beat out Austin Rivers and Roger Mason, he doesn’t deserve it) and the chance to prove he’s one of the most underutilized pure shooters in all of basketball. I’m a fan of surrounding Anthony Davis with as many shooters as humanly possible.

Chances of a deal: Low

It might just be a vibe, but I get the sense New Orleans is perfectly happy letting their core gel, regardless of what’s going on in the standings. Maybe that’s smart. Until Gordon, Davis and Anderson play with each other more, it’s hard to get a sense of what they’ll need next to them going forward.

We’ll hit the Eastern Conference next week, but check back tomorrow for analysis on how a few All-Stars have changed the pick-and-roll.

ive been saying the ROCKETS needed to make a deal for Josh Smith for the past couple years. and now that we have Harden, Lin, Parsons and Asik, he would fit in perfectly with them. i just dont know if we have enough players with big enough contracts. id say trade delfino patterson and morris. maybe pick(s)
